TB6600 / HY-DIV268N-5A Problems, and possible solutions

[Doddy]

Phil,

These are the ones that I bought...

Although my seller went under the name of "bigger*gift", but we all know the Chinese are a little agile with their naming. I think the discriminator is the 50V and 5A rating.

I'd caution, however, the subject of this thread and that mine, bought April/17 required the opto-isolators replacing.

OK thanks, I just bought two that look just like that, with the higher voltage and current rating. I can replace the optos as this thread details.

Meanwhile, I just ran a large job at 2x speed and it made it through the job twice without tripping, so maybe I'll be OK for milling polystyrene - will wait a while before putting the actual lump of wood under it though!
